They replaced the injector on my car, but it didn't make any difference. They don't know what the problem is, and they are checking with the Subaru tech line.
I know this is an isolated incident, and I really don't think I made the wrong decision buying this car. I love driving it every day. When I have it! They gave me a loaner, and I'm racking up the miles on it, so I really can't complain too badly, but I miss it.
I'll post am update when I find out anything.
And, yes, I am the first owner. Bought it new Sept. 2010.
